Contrology Training in Patients With Non-Specific Neck Pain

Non-specific neck pain is a common musculoskeletal condition that may lead to pain, restricted cervical movement, functional disability, and altered head and neck posture. Forward head posture, commonly assessed through craniovertebral angle, is frequently associated with neck pain and may contribute to increased mechanical load on cervical structures. Exercise-based rehabilitation is commonly used for the management of non-specific neck pain; however, the effects of Contrology training on pain, cervical range of motion, disability, and craniovertebral angle require further investigation.

This study is designed as a single-center, two-arm, parallel-group randomized controlled trial. A total of 40 participants with non-specific neck pain will be recruited and randomly allocated into two equal groups. Group A will receive Contrology training, and Group B will receive conventional physiotherapy. The intervention period will be 12 weeks. Participants will be assessed at baseline, 4 weeks, 8 weeks, and 12 weeks.

The primary outcome will be craniovertebral angle, measured using standardized lateral-view digital photography. Secondary outcomes will include pain intensity measured by the Numeric Pain Rating Scale, neck-related disability measured by the Neck Disability Index, and cervical range of motion measured using a digital inclinometer and/or universal goniometer. The study will compare changes within each group over time and between groups to determine the effectiveness of Contrology training compared with conventional physiotherapy.

These points match your thesis protocol: randomized trial, 40 participants, Contrology versus conventional physiotherapy, and outcomes including NPRS, NDI, CVA, and cervical ROM assessed across baseline, 4, 8, and 12 weeks.
